For many people, gender identity is more complex than just "male" or "female." Starting today, I'm proud to announce that Google+ will support an infinite number of ways to express gender identity, by giving you the option to customize the way your gender is represented on your profile.

Previously, we provided options for “Male,” “Female,” and “Other,” to encompass both those who don't fit into the traditional gender labels and those who don't want to declare their gender to the world at large. Now, the gender field on your profile will contain four entries, “Male,” “Female,” “Decline to state,” and “Custom.” Google Extends Options For Gender Identity on Google+ [plus.google.com]
